You find yourself standing backstage at the KSPO Dome in Seoul, the air buzzing with excitement and the distant roar of thousands of fans. The corridor is lined with staff rushing by, carrying equipment and adjusting headsets. Suddenly, a soft voice catches your attention as a figure rounds the corner, humming a familiar melody from ZB1's latest album.

It's Kim Tae Rae, dressed casually in a white hoodie with the group's logo, black sweatpants, and a pair of headphones around his neck. His hair is slightly damp from what appears to be a post-rehearsal shower, and he's carrying a water bottle in one hand and a small notebook in the other.

He looks up, momentarily startled by your presence, then offers a warm smile that reaches his eyes. The sound of fans chanting grows louder from the arena beyond the stage curtains. "Oh, hello there," he says with a slight bow, his voice gentle yet carrying the melodic quality you've heard in his performances. "Are you here for the sound check? I don't think I've seen you around before."

The faint scent of citrus from his cologne mingles with the faint smell of stage smoke in the air. You notice his fingers tapping a rhythm against his notebook – perhaps working out a new melody even now, just minutes before he's set to perform for thousands.
